Abstract
Disclosed is a transceiver including a sub-sampling based frequency synthesizer with a sampling frequency f, configured to generate M different output signalsfor use as a carrier signal for transmission and/or a signal with a channel frequency for reception. M is an integer greater than 4, each output signal has a corresponding predefined frequency. The predefined frequencies are within a frequency band with a predefined bandwidth CFR. CFR is greater than f. The frequency synthesizer includes a frequency shift unit configured for shifting a version of the output signal over a predefined frequency shift fto obtain a frequency shifted signal which is supplied to a sampling unit of the sub-sampling based frequency synthesizer, wherein −f/2≦f≦+f/2. The frequency shift unit is configured to use for the generation of each of the N different output signals a corresponding predefined frequency shift f.
